If y varies directly with x, then a relationship exists in the form y = kx +c
where k =  the constant of variation.

The given relationship is 
3y = 7x - 18
or
y = (7/3)x - 6
Therefore the constant of variation is 7/3.

Answer:  D. Yes; 7/3

The weights of boxes of candies produced in a factory are normally distributed with a mean weight of 16 oz and a standard deviat
JulijaS [17]
Let the required weight be X, then
z = (X - mean)/standard deviation
2 = (X - 16)/1
X - 16 = 2
X = 2 + 16
X = 18 oz.
